GAS-HEATED ROTARY BRUSH FOR STREET-CLEANING MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 506,501, dated October 10, 1893. Application filed April 1, 1893. Serial No. 468,725. (No model.)

To aZZ whom it may concern.-

Be it known that we, RICHARD A. HEALY and EDWARD D. OUNDELL, citizens of the United States, residing in the city of Paterson, 1n the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Gas-Heated Rotary Brushes for Street-Cleaning Machines and for Snow- Melting Purposes, of which the following is a specification.

Our invention relates to rotating brushes for use in a movable machine, mounted upon wheels, which may be moved rapidly over the surface of roads, both rail and common, as well as streets for the purpose of liquefying snow that may lie upon the same during or after a snow fall, the brush which is formed of 1ron or steel, revolving in a chamber formed on the under side of the platform of the truck or carriage, and which is made a combustion chamberforthe ignited gas and air from adjacent hurners. The wires forming the brushes absorb a part of the heat of the chamber and becoming red hot in their revolution and in them contact with the snow become cooled in the act of melting the same and heated again when they enter the chamber in their rotation. By this means. large amounts of snow mayberapidlyliquefied,inasmuchas besides dissolvlng the snow by contact with the heated brush wires, the snow is lifted up and thrown about in the annular chamber that surrounds the brush, which being filled with heated air and gas flame, is completely dissolved. Motion to rotate the brush may be obtained by means of a link belt chain in continuous connection with a driving sprocket wheel on one of the axles of the vehicle which rotates with the wheels, and a sprocket wheel on the center shaft or arbor of the brush.

It may be understood that all parts are preferably made of steel and iron to withstand heat, and that the brush may be capable of ab ust-ment with respect to,height that may be necessary for uneven roads, or streets. We accomplish these results by the various devlcesillustrated in the accompanying draw lngs, in which- Figure l is a side elevation, showing part of a wheeled carriage with brush located in its bearings and connected by belt to driving by the hand wheel and screw A.

axle. Fig. 2 is a plan view of the same. Fig.

3 is a transverse sectional view of machine through central brush.

Similar letters have reference to similar parts.

We will now proceed to describe the construction, and operation of'our newly invented gas heated rotary brush.

B Fig. 1 represents the frame of a wheeled vehicle to each side of which an adjustable bracket or hanger is secured, in the bearings of which, A is located the arbor A of the brush A and which is vertically adjustable Secured on the arbor A by the set screws A spiders P are located, upon which are secured, by the bolts P and lugs A the cylindrical drums A, which are made in sections to accommodate the width of face required for the brush, three or more being necessary. Six or more sections of brushes may be arranged circumferentially on the cylinders or drums and are extended the whole width of the drum longitudinally.

The sides of the vehicle are provided with the protecting shields, B, B, and the under Side is covered,forming a chamber,by the plates E, E, plates being curved in the center longitudinally to a radius larger than that of the extremity of the brush pins 0, 0 so as to form the space E for combustion of the unexpended gases from the burners G and G, which are located a certain distance from the drum or brush A.

To the driving axle F- which with its wheels B revolve in the bearings 13*, is secured a sprocket wheel F a similar but smaller sprocket wheel F being secured to the shaft, or arbor A of the drum, or brush A. The chain or link belt F being continuous, connects the driving motion from the wheel F to the wheel F and allows a different rate of revolution for each wheel, or shaft, as shown in Figs. 1 and 2 suitable holes or slots being formed in the cover plates E, to permit the rotation of the wheel F and the passage of the chains F In operation, when the vehicle is in motion forward, the wheels B and axles F revolve, as also the sprocket wheel F which by the link belt, or chain F imparts an accelerated rotary motion to the wheel F shaft A, and

rotary drum or brush A,'the brush points 0 0 being adjusted by the hand wheel, and screw A, so that contact with the snow may be secured. The gas and atmospheric air issuing from the orifice of the burners G, and G being ignited; the flame is directed directly upon the sides of the drum A, and the surplus and rising heated gases rise and fill the semi-annularcombustion chamber E. The points of the wires 0 as also their entire length attaining a red heat, strike and lift the snow, throwing it up into the chamber E, as well as dissolving, or liquefying it by direct contact; by this means the wires or brushes are kept at a red heat, although, alternately passing through the body of the snow upon the road.

By this arrangement the rapidity of liquefaction is limited only, by the degree of heat maintained in the chamber E, and the number of revolutions of the brush A, the pins 0, C acting as knives to divide the snow, as well as blades to throw it into the chamber E.

Having described the construction of our newly-invented-gas heated rotary brush for street-cleaning machines, what We claim as new, and desire to secure by Letters Patent, is as follows:

1. The combination of a wheel carriage or vehicle; provided with a covered combustion chamber; with a rotary brush or brushes contained therein, gas burners arranged on each side of said brushes; rotary motion being communicated to said brushes by sprocket wheels on the brush shaft and wheel axles connected by a linked belt or chain, said brush shaft being abjustable in its bearings, substantially as specified.

2. The combination of the platform B, wheels B axles F, side shields B, cover plates E, of a wheeled vehicle with the rotary brush A, mounted on shaft A, gas burners G. G. hot air chamber E, sprocket wheels F F chain F bracket A bearing A adj usting screw and wheel A substantially as specified.

3. A rotary brush mounted in adjustable bearings located upon a car or vehicle and gas. burners arranged on each side of the same, said brush being constructed of incombustible material substantially as and for the purposes specified.
